In The Great Gatsby, what does Gatsby flaunt at Tom when he talks to him, and what was Tom's hypocritical remark?Chapter 6

Your question seems more related to the dramatic hotel scene that occurs in Chapter VII when Tom, Daisy, Gatsby, Nick, and Jordan have driven into New York City to escape the heat and boredom of summer. After taking part of a suite at the Plaza, the irritable group orders drinks; conversation ensues, leading to the unavoidable confrontation between Tom and Gatsby. Gatsby tells Tom that Daisy never loved him, even when she married him, because she has loved Gatsby and has continued to love him for all of the last five years. Gatsby then taunts Tom:

No, we couldn't meet [in the past five years]. But both of us loved each other all that time, old sport, and you didn't know. I used to laugh sometimes . . . to think that you didn't know.

Tom rejects everything Gatsby just said, insisting his wife loved him then and loves him now. Then, Tom assumes the role of faithful husband:

And what's more, I love Daisy too. Once in a while I go off on a spree and make a fool of myself, but I always come back, and in my heart I love her all the time.

Tom's hypocrisy is more than Daisy can tolerate. "You're revolting," she says to her husband.
